A series of instrumental analyses is described for verification of apple juice authenticity. Liquid chromatography is used to determine sugars and individual phenolics, atomic absorption spectroscopy is used to determine K standard AOAC [Association of Official Analytical Chemists] methods are used to test for polyphenolics and formol indexes and stable C isotope ratio analysis (SCIRA) is used to detect high fructose corn syrup. These tests will identify fraudulent, but not poorly processed, apple juice.
